Chimaera with greenish yellow margins or irregular patches on leaves and calyces. Flowers paler than in unvariegated plants. Lemon-scented.

Reverts easily to green.

This cultivar name is wrongly used in Australia. The original T. 'Aureus' is believed to have uniformly yellowish leaves, not gold-edged ones. Since this plant is not in Australia and a name for the Australian plant has not been registered, it seems prudent to retain 'Aureus' for now.
